The Physics and Astronomy Department of Dordt University prepares students to understand the physical aspect of creation in the context of acknowledging God as creator and sustainer of all, recognizing his self-revelation not only in scripture but also in his creation. We seek to prepare students to take up the task of unfolding the creation both in graduate study and in the workplace.
